The T41-EP (aka T41) is a robust 20W SSB and CW SDR transceiver, three years in the making by Jack Purdum W8TEE and Al Peter AC8GY. It is an open source project and the radio is designed to be an experimenters platform. Frequently-used settings are quickly changed using the front panel switch matrix. Other, less frequently-changed settings, are modified using a simple menu system. The settings are "set-and-forget" since they are stored in EEPROM. Software and hardware solutions can be easily be changed so experimenters can tailor the rig to meet individual needs. Jack and Al have done their best to make the radio a flexible platform to bring ideas to life and more fun, enjoyment to the hobby.
